Check your line of sight if you are using a scope. If you find that you are lifting your head off the stock to see clearly through your scope, that will cause accuracy problems. This problem can be cheaply remedied with a comb raising kit. The kit will allow you to custom the height of comb on your stock. This will help achieve a good cheek weld, increasing accuracy.
